l lill GASTER-SLIDE.

Application filed August 16, 1913.

To all whom it may concern Be it known that I, PHILLIP KnnnAUE-n, of the city of New York, county of Kings, and State of New York, have invented cer. tain new 4and useful Improvements in Caster-Slides, of which the following is a specification.

My invention relates Vto caster slides, particularly those which are permanently attached to the legs of articles oi urniture.

The objects of my invention are to provide an improved caster slide which will be strong and light, and which will be cheap and easy to manufz etui-e.

.Viith the above objects in View, the present invention consists of the arrangement of parts more fully described hereinafter and illustrated in the accompanying drawings, in which,

Figure l is a top View of one form of my invention. Fig. '2 is a front view and Fig. 3 is ay bottom view ot' the same. Fig. 4. is a .vertical section of Figs. l and 3. Fig. 5 is .a View of my invention as it appears attached lto the ler,r ofa piece of furniture.

My improved caster slide is made of one piece of metal, 'preferably the ordinary 'market steel or iron for the sake of cheapness. 4

Referring more specifically tothe drawings, the prongs l are adapted to enter and to retain their position in the leg of a piece of furniture. The sustaining portion 2 of the caster slide is' indented at its center preferably inthe form of a spherical segment as shown at 3, Figs.` l, f, 3, l and 5. The height of the top of the indent 3 is made such that the said top will be at the same height and level with the rim 4t of the sustaining portion 2, so that when the improved caster slide is attached to the legv of the article of furniture, the part- 3 will be in contact with the bottom of the leg 5,

as shown in Fig.

vl ani aware that caster slides having prongs have been made ot one piece of metal. However, they have no reinforcing indents and cannot be made of the ordinary steel or iron, for they would then lose their supporting qualities and their rigidity, which has heretofore been imparted by some special process, such as tempering or the use of high carbon steel. y

The indent serves to take some ot the weight oit the article of furniture -from that portion G oi' the caster slide which is in Contact with the i'loor or-iloor covering, by

acting' as a reinforcing arch. For this rea` son it is possible to construct my improved slide of light and cheap metal., sui'iicient rigidity being` obtained by means of the reinforcing indents which give the slide a sinuous crossl section, thereby allowing the better distribution of the load.

What I claim is:

A metallic caster slide constructed from a single blank of material of .circular outline, and formed to provide a ring of substantially U-shaped cross sectional configuration, the innermost annular Wall of which merges toward the center of said ring and provides cent ally arranged semispherical portion reversely disposed With respect to the U-curvature oil said ring, said segment providinga a bearing surface for the article to which the slide is attached and lying in the same plane 'with the upper edge of the outermost wall, thereby quickly distributing the Weight of said article over the entire area of the caster, and atti'iching prongs rising from said outer wall at diametri ally opposite points.
